My cub sat a loooooong time , over 17 years ,just prior to the long sit I had the starter rebuilt at a proffessional start/gen/alt shop they do great work , after the long sit she started and then it stopped (the starter) , so I took starter apart for inspection and besides some dust all parts look new and ready to work so I put starter in a vice attach a ground wire from 12 volt boost end start hit , tattach the positive to the hoot lug and all I get is a hmmm and no rotation ,,,,,,,,, am I doing it right? with 12 volt boost negitive ground if all parts are working the starter should turn

Took brushes off again they look clean and new reinstalled , put my 200 amp boost starter on an I get hmmmmmmm then I bolt it to the cub pull the ring and instantly she fires up all good now Thanks fellas
